Description
The technical field is as follows:
the invention relates to the technical field of constructional engineering, in particular to a semi-fabricated light steel-foam concrete combined wall and a using method thereof.
Background art:
at present, many buildings are constructed from reinforced concrete, however, the construction is self-weight. The gravity density of the general reinforced concrete is about 25kN/m3And has a greater weight than both masonry and wood, and although having a lower weight than steel, the cross-sectional dimensions of the structure are larger, so that its own weight far exceeds the weight of steel structures of the same span or height. Also, this structure has poor crack resistance. As described above, the tensile strength of concrete is very low, and thus, a general reinforced concrete structure often works with cracks. Although the presence of cracks does not necessarily mean that the structure is damaged, it affects the durability and aesthetics of the structure. When the number of cracks is large and the width of the cracks is wide, an unsafe feeling is also brought to people. Finally, the steel-concrete structure itself is brittle. The brittleness of concrete increases with increasing strength grade of concrete.
In order to effectively solve the problems caused by the structure, some building projects have used light steel-foam concrete walls to replace masonry walls and steel-concrete structure walls, so that the defects of the structure are avoided to a great extent. However, the application of the light steel-foam composite wall body in practical engineering causes other problems. The method is characterized in that the lightweight steel-foam concrete wall body is processed in a factory, the foam concrete is poured into the lightweight steel-foam concrete wall body, the self weight of the lightweight steel-foam concrete wall body is large, but no method is provided for drilling holes in the wall body as a whole, so that great inconvenience is brought to the hoisting and transportation processes, the strength of the wall body is limited, the wall body can deform without paying attention to the hoisting process, and the strength of the wall body is reduced. Secondly, because the wall body is prefabricated in a factory, the wall body is difficult to be connected with the top beam and the ground beam in a construction site. Finally, as the foam concrete in the combined wall is poured in a factory, the disadvantages of precast concrete can occur when the foam concrete is applied to actual work: i.e. the load capacity of the wall as a whole is inferior to cast-in-place concrete structures.
Therefore, a more applicable semi-fabricated light steel-foam concrete combined wall and a using method thereof need to be provided to meet the using requirements.
